Abstract

Current swimmers or divers, especially for anglers fishing, which develops a transverse force perpendicular to the flow in relative to itself flowing liquid, characterized in that at least a part of the Strömungsschwimmers or -dauchers as rotor (R) in the flow (S ) so that the transverse force (F) is formed by the Magnus effect.

Description

The Invention relates to a swimmer or diver who in relative flowing to himself liquid a transverse force developed perpendicular to the flow (Strömungsschwimmer or diver).

flow float This species is used in particular as a bite indicator (poses) for fishing in streams, rivers or channels used.

By their essential feature of a transverse to the flow direction Force component is enabled that a z. B. from a river bank towards the middle of the river ejected float by the flow is not completely on the shore driven back but that depends on it the string length and the location of the angler on the shore at any point can be positioned in the river. So it's going to be a permanent one Fishing in all river areas allows, what with conventional Floats not possible is.

Drift diver The type mentioned are especially when towing fishing from the driving Boot out. Here is the transverse force developed by the diver used to B. a bait without heavy lead weights in deeper water layers lead to can or to keep it out of the swirling fairway can.

It Applications are also known in which the lateral forces of flow divers used to increase the span of towed nets.

• • Zug-Elemente für mobile Treibsperren (z. B. auf Flüssen),
• • mobile Messdaten-Erfassungssysteme, die auch ohne Motor positioniert werden können (z. B. zur Erfassung der Strömungsgeschwindigkeit),
• • Fluss-Bojen, die ohne Befestigung am Grund auskommen und daher variierbar in der Position sind,
• • Antrieb von Fähren zur Überquerung von Flüssen ohne Motorkraft und daher besonders umweltfreundliches Fortbewegungsmittel.

Flow swimmers or divers can also be used as z. B .:

• • train elements for mobile driving barriers (eg on rivers),
• • mobile measurement data acquisition systems that can also be positioned without a motor (eg for measuring the flow velocity),
• • river buoys, which manage without attachment to the bottom and are therefore variable in position,
• • Driving ferries to cross rivers without engine power and therefore particularly environmentally friendly means of transportation.

Anglers who are fluent in the fishing industry and produce a force component transverse to the direction of flow by means of baffle-like devices (such as rudders, keels or guide plates, for example) are known. US 1466601 A . DE 6601584 U . DE 9313796 U1 ). In some cases wing-like cross-sections are also used for these devices (eg. DE 19963963 A1 . WO 03056915 A1 ). Flow diver with baffle-like devices are for. In US 1361067 A . US 3135065 A or DE 29814933 U1 described.

In addition, motorized floats are known with screw drive, which can also be used as a Strömungsschwimmer (eg. DE 9313796 U1 . JP 08019357 A ).

at the well-known flow swimmers or divers are the force across the flow considerably from the respective one Geometry of the float or diver (eg the angle of attack the baffle-like device or the position of the cord attachment). The optimum angle of attack and / or the optimum line attachment position must be Often set and tested in several passes before use become.

Also in the production is an elevated one Effort required, to provide optimal geometry.

Of Furthermore, the holding force of the known Strömungsschwimmer varies or diver, the z. B. be held with a string, with the Angle of the baffle-like device to the flow. Thereby For example, in angling, the use of bite indicators, the changing one Cord pulling forces appeal, difficult. Furthermore can already at low angles of attack by weaker turbulence a tipping over of the angle of attack. This is the float or divers restless in the current and the targeted fishing for a particular spot or track is difficult.

Of the The invention is therefore based on the object, a flow float or - diver too develop, in which the mentioned disadvantages avoided or clear are reduced and in particular the effort for the adjustment of baffles deleted.

The The object is achieved in that At least a part of the Strömungsschwimmers or diver as a rotor in the flow turns so that the transverse force is formed by the Magnus effect.

you namely achieved in that rigid to the flow oriented fins omitted and thus a transverse force regardless of corresponding angles of attack acts. additionally is due to the rotary motion a certain cleaning effect against flotsam achieved, which after some time often on conventional flow swimmers or divers.

Especially in the case of flow divers, rotor shapes are possible which offer improved behavior at ground contact show: the rotor then rolls more or less over the ground, whereby the risk of entanglement is reduced.

Furthermore is for Flow swimmers and divers a much freer shape design possible, since the fluidic Conditions for the transverse force is less dependent on a particular shape of the rotor, but essentially, that and how fast he turns.

In a preferred execution The invention provides the drive energy for the rotational movement of the rotor from the flow energy won the liquid. This is eliminated an additional Energy supply, what small and compact stream swimmers or divers allows. In addition, can simply based on the rotational speed on the flow velocity inferred become.

Of the flow drive for the Rotational motion can be realized so that by the flow Torque acts directly on the rotor. A basic principle for this is that the flow friction on the two halves of the rotor passing through one of rotor axis of rotation Z and flow direction S clamped cutting plane is formed, and is different that the resulting torque D drives the rotor R (drive by flow friction difference). This is natural to note that an inhibition of rotary motion by a particularly smooth running storage of the rotor is avoided.

This Principle of the flow drive can with a variety of z. T. very different forms be implemented of the rotor. So the rotor, for example, in Cross section perpendicular to the axis of rotation both a contiguous surface as also separate partial surfaces exhibit.

Besides that is it is possible with this principle, small and compact as well as cheap to be manufactured flow float and diver to realize, since the further cultivation of possibly elaborate Flow energy extraction machine (such as propellers with transmission gearbox) is eliminated.

A preferred embodiment the drive by flow friction difference is achieved by the direction of the torque D acting on the Rotor acts independently from the angle of rotation of the rotor about its axis of rotation Z with respect to flow direction S is.

So is achieved during the rotation of the rotor by 360 ° in each Rotary position only one torque in one direction of rotation is present. Angle of rotation where the torque direction changes (dead points or angle ranges with counter torque), thereby avoiding what a steady Rotational motion conducive is.

Of the Driving the rotary motion can alternatively also by an engine (eg electric motor). This makes it possible to have a more Transverse force in the flow to achieve than with flow-driven Rotational motion, since the rotational speed is not dependent on the flow velocity depends.

there are the choice of the rotor shape with this type of drive hardly limits set, because the Magnus effect in a rotary motion of an arbitrarily shaped Object in a current occurs.

Especially when used as a bite indicator for angling is one preferred embodiment of the current float beneficial to the rotational movement of the rotor with signaling devices (eg for position display) combined. Especially at night fishing or when fishing with backlight, the position of a similar to a lighthouse flashing or flashing float much easier through the Anglers are recognized. This can be particularly easy and without additional energy be achieved by an array of apertures or reflectors. This preferred embodiment in principle also applies to Drift Diver. Here, however, the advantage of increased visibility is above all at greater depth rather in the form of an improved lock effect on fish.

For example Of course, for the purpose of alternative design it is also possible, a current float or diver with multiple rotors to build.

1 and 2 show an example of a Strömungsschwimmer, whose rotational movement D is driven by a flow S and is designed especially for fishing at night or at dusk.

It consists essentially of a buoyancy body of rigid foam material (eg., Polyurethane hard foam), which is identical in this example with the rotor R, a thin, corrosion-free metal shaft W and the holding device H. The rotor R has a Shape similar to that of an ellipsoidal radial milling cutter ( 1 and 2 ). The shaft W is oriented and positioned identically to the rotation axis Z. The shaft W and thus the entire rotor R fixedly connected to it are fastened to the suspension device H at two suspension points, namely the two bearings L, freely rotatable about the rotation axis Z.

The Holding device H consists of a dimensionally stable and corrosion-free Wire, the two eyelets for the Attachment or guide the retaining cord (fishing line A) has. On the upper extension the wave W is a glow stick holder G attached. He leaves that Light of an inserted kink light K only in two opposite 90 ° wide angle ranges exit - the two other 90 ° areas are covered by the glow plug G. To be more efficient Light usage is the holder G inside mirrored. By this arrangement arises during a complete rotation of the rotor R, a flare with two light and dark phases (lighthouse effect).

In order to a use of z. B. both banks of a river is possible, is it u. U. advantageous, a right and a left variant of To provide holding device H. The flow float can be removed by pulling of the glow stick holder G and easy pulling apart of the flexible Holding device H can be easily freed from the same.

On the surface of the rotor R now act due to the flowing relative to her liquid N frictional forces. These frictional forces depend on the orientation of the surface or surface structure to the flow direction S:
the proportion of liquid flowing against the sawtooth direction (in 2 : above), generates more frictional forces than that flowing with its direction (in 2 : down around). The result is a torque D, which has a permanent rotational movement of the rotor R about the rotation axis Z result.

By this rotational movement D in the flow S now acts a transverse force F on the rotor R, whose direction is perpendicular to the flow direction S and perpendicular to the axis of rotation Z is oriented (Magnus effect).

In 3 and 4 is a flow diver shown that works on the same principle.

He also consists of a rotor R with shaft W and a holding device H. The rotor R is in turn freely rotatable with two bearings L on the Holding device H attached. In contrast to the current float Here, the rotor blades are preferably made of a material the one higher weight as the liquid has (eg sheet in water).

5 to 10 show examples of other forms of rotors.

5 characterizes a rotor having partially flexible, movable leaves B. These fold by the flow pressure to the outside, when the flow is opposite to the sheet B (in 5 around). If the flow lies in the direction of the sheet (in 5 down around), so the leaves put on the rotor by the flow pressure.

One Leaf with such behavior can easily be elongated foil piece be realized, of which a narrow edge strip on the surface of a spherical Rotor is glued so that the edge strip along a longitude runs. The foil piece then either works out bulbous in the flow or lays down to the Rotor on (where it waves a bit).

6 to 10 illustrate examples of rigid rotors. Represent 9 and 10 a rotor geometry that should have an integer multiple of the drawn shape with respect to its extension in the direction of the axis of rotation Z (helical rotor). This ensures that the torque D is always the same at every angle.

11 and 12 describe an electrically driven motor-driven float. The rotor R is driven here by a motor M, which is powered by the batteries E with energy. The shaft W is fixedly connected to the rotor of the motor M, has the same axis of rotation Z and is suspended in the two motor bearings L. The stator of the motor M is fixed to the rotor R. The wave W is opposite to the rotor R to the outside sealed with a smooth rubber lip. In addition, the penetration of liquid through the otherwise airtight structure of the rotor R is prevented (openings only down). In contrast to the flow-driven Strömungsschwimmern the rotor R has a more or less smooth ellipsoidal surface.

As well as in 1 shown flow-driven Strömungsschwimmer the motor-Strömungsschwimmer is equipped with a signaling unit consisting of holder G and Kick light K.

For all rotor examples It should be noted that the transverse force F in relation to the drift force of the Strömungsschwimmers or diver in the direction of flow significantly of parameters such as rotor shape, rotor size, flow velocity, type the liquid etc. depend can. Of such parameters, in particular, the flow-driven Rotational motion of a rotor strongly dependent. In this respect put in the Drawings, implicit angle information between retaining cord A and flow direction S no general effective efficiency statement represents.
